APPARATUS FOR SIZING AND DRYING COTTON-BATTING.

Specification of Letters Patent N 0. 7,533, dated July 30,1850.

To all whom, it may concern:

Be it known that I, ELIAs P. RIDER, of the city, county, and State of New York, haveinvented a new and useful combination of machinery for selvaging, j heating, ironing, glazing, drying, delivering, measuring, and cutting into lengths cottOnwad ding by a} continuous process by steam or other power, called .Riders Steam WVadding-Machine]? lows, lreference beingi had to the annexed drawings of the same, making part of this specification.

Figure 1, is a vertical longitudinal section ofthe machinery. Fig. 2, is a vertical transverse section on the line mum, of Fig. l, showingthe incl ned plates for making the.

selvage and the hollow cylinder heated by Steflm p.l.pS, &C. Fig. 3, is a vertical transverse section on the llne .2, a, showing the. Fig. 4, 1s a:hor1zontal floating cylinder. sectiognal view showing the curved or twisted guide platesfor turning the ragged edges of the bat and the receiving cylinder against which. they are ironed by the cylinder 0 shown inFig. 1., i

Simil r lettersfin the several figures refer to like parts. i

The linesA, indicate the stationaryparts of the structure containing the machinery to effect the objects above stated, :and which may be made in any convenient way. i i.

The line B represents the continuous sheet of wedding undergoing the several opera tions of having. the selvages formed, heating, ironing, andglazing onboth sides and drying with steam.

i The arrows show the direction the wadding takes during the performance of the operations.

The floors of the machine are shown. at

a, a, are two curved plates for turning the edges of the hat of cotton to form the continuous sheet passing to thereceiving cylinder; 6, the receiving cylinder c, the heated cylinder for heating and ironing the hat of; cotton; d, the compressing cylinder working against the steam cylinder. for. ironing the Cotton bat:

previous to glazing the same.

The object of heating and ironing the bat is to cause the sizing to adhere to anincreased numloer of fibers. The bat of cotton which is described as folsticking to the made to revolve with .quired distance from the surface of the compressing cylinder'for the purpose of delivering the sizing in a light, transparent, and

of wadding previous to its has heretofore been glazed in a loose and cold state.

e is hollow floating cylinder revolving in the glazing material and raised toward the compressing cylinder d for imparting the glaze to the heated and ironed hat of cotton.

This. floating cylinder has circular lips or check rings 11,,12, formed around its periphery next its ends designed to turn against the periphery of preventing the surfaces of the floating and compressing cylinders coming together. The gudgeons of this floating cylinder turn in the ends of vibrating levers Z whose fulcra areinserted into. the ends of the sizing trough 777A, or in any convenient place. In Fig. 1 this roller is representedas imparting sizing to the cotton batting. The dotted lines in the same figure represent the lever turned to nearly an upright position and the Lfloating cylinder immersed in the sizing for thepurpose of preventing the glazing material drying or cotton in case of stopping the machine. V n

The check rings maybe held incontact with the compressingcylinder with any re quiredrlegl'ee of pressure by the application of SOFGXVSyWGlghtSfOI sprlngs to the leveryor to the axle of the floating roller,

or by other means equally effective.

The sizing or floating cylinder may be its surface at the reeven manner without crushing or pressing the particles of sizinginto the cotton and thereby destroying its fine gloss.

72, is an endless apron passing around r011 ers (f) arrangedin a heated chamber (i) inclining upward from the'glazing appara tus toward the chimney (7') which is arranged'in an upright-position at the ends or center of the structure; said chamber being heated by steam passing through a pipe or pipes g placed in said chamberthe steam being received from the end of theheating cylinder i a The sides, top and bottom, of the heated chamber-z are composed of wood, or other the compressing cylinder for the purpose of suitable nonconducting material for confining theheat required todry the sizing. The chimney j is for the purpose of drawpipes and heating chamber, and other ap-' and the heated or ironing cylinder 0, are

twisted somewhat after the form of a section of a screw and are placed directly in front of the receiving cylinder Z) and beneath the ironing cylinder C.

As the sheet of batting comes from the carding engine, its ragged edges strike against the aforesaid curved plates and are turned and folded against the even part of the bat, in which state the bat passes over the receiving cylinder and under the ironing cylinder when the edges are ironed down smooth and even as well as the whole surface of the bat, causing it to be of umform width and unbroken edges. 4

- At the opposite end of the frame or structure there is a similar arrangement of heating and ironing cylinder, compressing and floating cylinders, sizing trough, steam pendages for heating, ironing, and glazing the continuous bat of cotton on its opposlte side. There are, however, no curved plates. for turning the edges, as these are not required at this end of the machine.

Operation: The continuous sheet of batting passes from the carding engine (of the usual construction and arrangement) between the twisted or curved plates a where its ragged and thin edges are turned and selvages formed; and passes thence around the cylinders b, 0, where it is heated and ironed; and thence around the cylinder 01 where it is sized by the floating cylinder 0, which turns at a distance from d, nearly equal to the thickness of the bat; and thence through the lower portion of the heating chamber 7) to the heating, ironing and glazing cylinders at the opposite end of the structure where it is glazed in a similar manner, without pressure, on its opposite side, and, returning thence through the upper part of the drying chamber back and beyond the first named glazing apparatus descends and passes under the same to a graduated measuring table upon which it is measured and cut into any required number of lengths by a rotary, vibrating, or other knife, operated by any suitable mechanism, as fast as delivered from the glazing machine; from which table the pieces are removed to the proper receivers as fast as the pieces are cut from the continuous strip of wadding, thus avoiding the necessit of winding it into a roll and then unwin ing it in order to measure and cut it into lengths.

The object of using the trough and glazing cylinder in the position set forth below the compressing cylinder is to apply the glazing material above the center of the floating or glazing cylinder 0, thus preventing the action of the air upon a large proportion of the surface of the cylinder 6 and preventing the glaze sticking to the cylinder cl. This arrangement also facilitates the loading of'the cylinder 6 with glazing material and the imparting to the bat of cotton a heavy coat of glazing during the operation, of a light transparent characterthe glazing matter being raised fresh from the vat as the floating cylinder revolves with at least two thirds of its circumference constantly immersed during the operation of coating and only one third exposed to the air the whole circumference being immersed during a cessation of the operation of glazing which thus prevents the glaze from drying upon the floating cylinder.

I am aware that various combinations of mechanism for glazing cotton wadding have been patented and that one or tWo of the combinations has proved in part successful, I therefore do not mean to claim any part of said combinations.

What I claim as my invention and improvement on all other modes of glazing cotton wadding and desire to secure by Letters Patent is 1. Doubling or turning the ragged and uneven edges of the bat of cotton as it comes from the carding engine and pressing them down to form a smooth selvage as set forth by means of the curved plates at in combination with the cylinders 12 0, as described; or other equivalent means.

2. I claim heating and ironing the surface of the bat of cotton previous to being glazed for the purpose herein set forth, whether performed by the means herein 'described, or other equivalent means.

3. I likewise claim making the floating cylinder with check rings, or their equivalents, in the manner and for the purpose described.

4. I claim passing the bat through a space between the floating cylinder and compressive cylinder and imparting the sizing to the bat of cotton without pressure as described.

5. I claim making the drying chamber a doubleinclined plane in combination-with the chimney constructed as aforesaid for, the purpose of increasing the circulation.

6. I also claim the peculiar combination of the heating, selvaging, ironing, and glaz ing and drying apparatus; by which the bat of cotton, as it comes from the carding engine, is selvaged, ironed, glazed and'steam dried by a continuous process, as herein signed my name before two subscribing witfully set forth, the sizing vat being placed nesses.

directly beneath the compressive cylinder so i that the sizing can be introduced fresh from RIDER the vet to the bat as it comes from the iron- WVitnesses:

ing cylinder, as described. WM. P. ELLIOTT,
